It did cause data loss, and we can not backfill because the disk was full so the logs were not written.

Thanks Nuria.

Did this cause data loss and if so, is there a plan to backfill?

Team:

As you might know we have swapped EL old vanadium box to a a never, more resilient one. 

This new box had less disk space and the move caused a small outage due to a bug already present on EL code that was not apparent on vanadium.
